Hi Wilcre,

i'm using GT-I9300 with AT&T monthy service. do you have any recommend how can i update my account and profile with ATT ? i used a lot of web and data that's why have to stick with monthy plan so i can get unlimited data but still cannot get 4G because of international phone ?

Re: International Samsung S3's phone cannot get 4G

that's sad, but i was told by ATT customer service at ATT store, if i can bring my freind that using S3 which's not international S3 and ATT can just scan EMIE to my account then i will get 4G cause they just need to update my data to 4G .. is it true?

the i9300 is not an LTE phone. it is a generic GSM phone that does not have the radio equipment for LTE.

Actually, the phone is compatible with AT&T's HSPA+ network, not just GSM.

But your main point is true, that the international version does not have LTE. They went quad core Tegra3, which did not have LTE support at the time. AT&T want dual core Snapdragon S4 for their version, for the main reason that the S4 chipset supported LTE.

HSPA+ will still get you around 2 to 5 Mbps in a lot of places (faster in some places). Plenty fast enough for most tasks. Some have even complained that LTE while faster, uses more battery.

According to this,your phone is only compatible with the 800, 1800 and 2600 Mhz LTE bands. AT&T uses the 2100 MHz band for LTE. Therefore, the phone is not compatible with AT&T's LTE network. This is fixed in hardware, and cannot be modified through software. Sorry to say, if you were relying on the phone working on LTE, you should have done more research before purchasing.

You are actually a little bit lucky you are even getting HSPA. Your phone is only compatible with the 850, 900 and 2100 MHz bands for 3G. AT&T uses 850 and 1900 MHz for 3G. So you must be in a 850 MHz market. You might find yourself with only EDGE (no HSPA) if you leave the area, and enter an area where AT&T is only using the 1900 MHz band for 3G. Although I think the 850 MHz 3G band is the more common one, and I also think AT&T is trying to migrate the 1900 areas over to 850 (so it will get better for you, rather than worse).

I have a Samsung Galaxy S3 (GT-i9305) that was purchased in Europe and is unlocked. I understand it is capable of the following data frequency spectrum...

2G - GSM 850 / 900 / 1800 / 1900 MHz

3G - HSDPA 850 / 900 / 2100 MHz

4G - LTE 800 / 1800 / 2600 MHz

I am currently in Montgomery, Alabama and was expecting to pull better data speed than what I am able to pull currently, which is just Edge/2G. Is it possible to get 3G or even 4G speeds from AT&T in this area on my Samsung Galaxy S3 (GT-i9305)?

From AT&T tech support on the phone earlier today they mentioned extending their 4G service to pre-paid/Go phone users.

Can you please help shed some light on their usage of the spectrum in the Montgomery area? Or is the throttled down data speed aspect associated with my account, and can be easily fixed via administrative internal system controls?
